Use the Toolspace Survey tab to create new instrument setups.
You can create a point using an angle turned from either a specified reference line or a previously determined backsight point. Additionally, you can also use a vertical angle or vertical distance to locate the point.
To create a new setup
- In the SurveyToolspace tab, right-click on the Setups collection and click New to display the New Setup dialog box.
- Enter the station point for the setup.
Note: If you enter a non-existent station point, you are prompted to create a point and the New Control Point dialog box is displayed where you can create a new station point.
- Enter the backsight point for the setup. When this column contains a valid entry, the Backsight Direction column displays the calculated backsight direction value and is read-only.
Note: If you enter a non-existent backsight point, you are prompted to create a point and the New Control Point dialog box is displayed from which you can create a new backsight point.
Note: Setups can be created using the names of Survey Points that exist in the Survey Database. Enter the point names in the Station Point and Backsight Point fields.
- Enter a backsight direction. This field is read-only if the Backsight Point column contains a valid point number.
- Enter the backsight orientation angle for the setup.
Note: This is the reference angle for all angle observations except Face1 and Face2 angles.
- Enter the measured instrument (theodolite) height. This is typically measured from the center of the theodolite optics to the setup point on the ground.
- Click OK to create the new setup.
To create a setup using the survey command language
- In Toolspace, on the Survey tab, right-click on the network that you want to add control points to. Click Survey Command Window.
- At the Command line, enter:
STA [point] (instrument height) (description)
Example
This example sets the instrument on point 1. It is 5.1 feet above ground elevation. Therefore, the instrument elevation is 105.1 feet.
